Abstract

um aparelho de fechamento de apêndice atrial esquerdo para obstruir o apêndice atrial esquerdo, compreende uma placa de vedação e uma placa ancorada. a placa de vedação está em uma estrutura de malha e disposta com uma membrana de estrangulamento no interior, além disso, a placa de vedação adota um membro tubular para a fixação distal e é conectada com a placa de ancoragem pelo membro tubular. a extremidade proximal da placa de vedação é fixada com um fixador provido de uma estrutura que conecta um dispositivo de transporte, enquanto que a extremidade do membro tubular no outro lado da extremidade fixa da placa de vedação é disposta com uma pluralidade de hastes de suporte que estão se interceptando radialmente dispostas para formar a placa ancorada.
